Good Luck Bwitched because with the amount of Barb kits out there, fewer ppl are willing to pay a good amount for your armor now.It very unlikely you will recover your cost of the barb kits, leather and vendor rental fees from the sales of your armor. So many ppl have just stopped selling armor now cuz its not worth the investment anymore.
If you bought your kits at 2 mil a piece then every piece must start with a price of 133,000 (133,000 x 15 = 1,995,000)
For leather Barb its running 200k for 1k so 13,667 (13,667 x 15 = 205,000) must be add to every piece also.
133,000 + 13,667 = 146,667 is the base price for every piece you make. Just round it up to 150k starting price per piece
Total Resist is another factor in the pricing:
50-60 =100k
60-70 =200k
70-80 =350k
80-90 =500k
90 or better 5 mil or higher
Mods are another factor:
Maxed mods will add 75k-100k per mod
Related Mods i.e. LMC and LRC are related
2 related add 100k
3 related add 250k
4 related add 500k
You can also add Duro to each piece and add the cost of the POF to the total price of the piece.
So a piece with 20LRC, 8LMC, 2MR, 5 mana increase would be about 950k
500k + 300k + 150K =950k That's 500k for 4 related, 300k for 3 max mods, and 150k base price.
You can adjust for what you think is fair market value now but i hope that helps some.
